CAR-R00 F.

SPECIFICATION forming part of Letters Patent N 0. 722,817, dated March 17, 1903. Application filed February 17 1902. Serial No. 94,454. (No modeL) cars of all kinds, strong and durable, and cal-' culated to thoroughly protect the contents of the car to which it is applied.

' With the foregoing in mind the invention will be fully understood from the following description and claim when taken in conjunction with the accompanying drawings, in-

' tallic sheets and the pole section B, and rafters F are broken, with the result that the enwhichv V v Figure 1 is a plan view of my improved carroof with the upper course of boards partly broken away; Fig. 2, a side elevation;'Fig. 3,

a transverse section taken on line 3 3 of Figs. 1 and 2, and Fig. 4 a perspective view of one of the metallic sheets of the roof removed. Similar letters of reference designate corresponding parts in all of the severalviews of the drawings, referringto which- A is the lower section, and'Bthe upper sec-" tion, of the rid ge-pole of the roof. The ridgepole is thus formed by preference in order to lend increased strength to the roof and prevent the ceilingand lower course of boards from working loose when the car expands even if the caris insufficiently trussed. I desire it understood, however, that when desired the upper section B alone may be employed as the ridge-pole without departing from the scope of my invention.

0 is the lower course of boards, which are secured at their inner ends between the polesections A B; D, an upper course of boards, which are secured at their inner ends on the pole-section B; E E, purlins disposed longitudinally below and connected to the upper course of boards; F F, rafters connected to the purlins and pole-section B, and G G metallic sheets. 7

The pole-section B is provided in its sides with seats a, which are by preference slightly pitched or inclined upwardly, as shown, and

are designed to receive the correspondinglyinclined flanges bat the inner ends of the sheets G, while the rafters F are provided in their sides with ways or grooves c, which extend inwardly above the lower course of boards 0 and then upwardly and have for their purpose to receive the side flanges d of the sheets G, as shown by full lines-in Fig. 2 and dotted lines in Fig. 3. By virtue of this construction it 'will be observed that the sheetsG may be readily placed in position by shoving them inwardly at the sides of the car and as readily secured in position by nailing their depending ears 6 to the sides of the car; also, that the expansion of the car will operate to hold the sheets in position and against displacement even when the car is subjected to extraordinary rough'usage'." It willfurther be observed that the joints between the metry of water into the car through/the roof is absolutely precluded and the contents of the ing myself to forming the parts of the roof of any special material or materials, as materials 'of various kinds may be employed without departure from my invention. When desirable, the upper section B of the ridge-pole may be covered throughout its length with a sheet of metal f, Fig. 2, this in order to afiord protection when the car expands.

It will be readily appreciated that my improved roof while simple and inexpensive in construction is strong and durable and perfectly water-tight; also, that it is applicable to both new and old cars. When the improved roof is applied to an old car, the old roofboards of the car may be utilized as the lower course 0 of the new roof, provided they are sufficiently well preserved and sound.

Having described my invention, what I claim, and desire to secure by Letters Patent,

In the car-roof described, the combination of a ridge-pole having the inwardly and upwardly inclined seats a in its sides, an upper course of boards connected to the ridge-pole, a

lower course of boards also connected to the vertical side flanges 01 arranged in the vertiridge-pole, rafters Farranged transversely of cal portions of the grooves c in the rafters, the car with spaces between them and having and also having depending ears eat their outer the grooves c in their vertical sides; said grooves extending inwardly above the lower course of boards, and then upwardly, and the metallic sheets arranged on the lower course of boards and in the inwardly-extending portions of the grooves c in the rafters, and having inclined flanges b at their inner ends arranged in the seats a of the ridge-pole, and

ends connected to the sides of the roof.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.

CHARLES WESLEY OREES.
